. SLOT-PROTECTOR FOR SLUG-OPERATED MACHINES.

.Specification of Letters atent.

Patented Dec. 22, 1908.

Application led November 27, 1907. eal'No. 404,045.

cago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Slot-Protectors for Slug-Operated Machines, of .which the following is a specification.

The object of my invention is to provide a novel construction of devicefor preventing n the use of any other than a particular Jform of slug as a means for primarily actuating the mechanism of a slug-operatedvending or other machine;

In the accompanying drawing, Figure 1 shows my improved device by a broken view in side elevation with the particular shape of slug forv use therewith in full lines near the entrance to the chuteand by dotted lines inserted into the same, and Fig.' 2 shows the vdevice in front elevation regarded in the direction of the arrowon line 2 ,-Fig. 1.

, AThe device may be applied to the front wall, represented at 3, of any of the varieties of machine to he protected against the useof spurious slugs. t consists ot a chute 4 supported in inined position on a late 5 adapted to be fastened to the face o the wall 3 at an opening 6 therein'through which the lower end of the chuteprotrudes into the machinecasing; a chamber or housing 7 eXtendin laterally from the outer end of the chute anc having journaledin it a toothed wheel 8 of 'general star-shape, the teeth of which eX- tend from the chamber into the path through' the chute near its insertion-end, and a pair oi pins 9, 9 extending across the ath through the chute near its lower side a jacent to the wheel 8, forming a slug-insertion space between the pins and the wheel. The slug re quired for coperation with my improved device is represented at 10. It is of general star-shape and consists ot a disk provided.

with radial teeth. The diameter of the slug or token 10 is such as to adapt it to be inserted into the mouth of the chute and eny counter with one tooth a tooth of the wheel rotate the wheel and with the pins9, Whichlthe pins 9 permits the insertion into the chute of a spurious token small enough to clear said teeth and pins, the weight of such small token would be insufficient to operate the machine and its use, therefore, would not avail t-hepurpose of the user thereof; and no larger token, unless itjvlbe of, or approximately of, the shape and size represented, could be used, since"thel wheel 8 and outer pin 9 would arrest it in the insertio' end Voi" the chute, and the likelihood persons making tokens like the token I() for spurious use on machines equipped with my improved device is so remote as to render it a desirable protection.

WhatI claim as new and desire to secure by Letters Patent is:

1. A slug-insertion-slot protector for slug-1 operated slot-machines, com rising a chute extending in position to fee slugs through it by gravity, a housing extending laterally' from the outer end of the chute, a toothed wheell journaled in said housing to protrude into the path through the chute, and a pin crossing the chute adjacent to the wheel at the opposite side of said path and forming with said wheel a passage between them for a toothed-disk form of slug and adapted to turn such a slug by its encounter therewith into engagement with said wheel.

2. A slot-protector of the character described, comprising a chute,va housing ey!- tending from the outer end of the chute, a toot-hed wheel journaled in said housing to protrude int-o the chute at one side of the path through it, and a pair of pins crossing themchute adjacent to the wheel near the opposite side of said path and forming with the wheel a passage for a toothed-disk form of slug, for the purpose set forth.
